Patent number: 10502426Abstract: A fuel injector is provided for the radial introduction of a liquid fuel/air mixture to a combustor. The fuel injector includes a body having a frame that defines an inlet portion and an outlet member that defines an outlet portion. A fuel plenum is defined within the outlet member, and a fuel injection port, which communicates with the fuel plenum, is defined through the outlet member. A fuel supply conduit, fixed to the body, communicates between a source of liquid fuel and the fuel injection port, via the fuel plenum. Alternately, the fuel injector may include a swirl-inducing device mounted to the outlet member in communication with the fuel injection port, and a fuel supply conduit fixed to the swirl-inducing device. In this embodiment, the fuel supply conduit communicates between the fuel injection port and a source of a liquid fuel and water mixture, via the swirl-inducing device.Type: GrantFiled: May 12, 2017Date of Patent: December 10, 2019Assignee: General Electric CompanyInventors: Donald Timothy Lemon, Gilbert Otto Kraemer, Wei Chen, Marcus Byron Huffman, Ronnie Ray Pentecost

Patent number: 8646277Abstract: A combustor liner for a combustor of a turbine engine includes a single-walled generally cylindrical liner that extends from a head end to an aft end. A venturi is formed on the combustor liner at a location between the head and aft ends. The venturi is formed by first and second straight portions of the combustor liner that angle inward to form a reduced diameter portion. The combustor liner may also include an air deflector to deflect air down onto the exterior of the reduced diameter portion of the single-walled combustor liner. The combustor liner may also include dilution holes, and turbulator rings.Type: GrantFiled: February 19, 2010Date of Patent: February 11, 2014Assignee: General Electric CompanyInventors: Ronald James Chila, Donald Timothy Lemon

Patent number: 6951109Abstract: Variations in dilution air leakage paths in a gas turbine combustion liner assembly are minimized or eliminated to reduce emissions and variations in emissions from combustor to combustor. Leakage paths between the liner sleeve and venturi outer liner are minimized by using additional rivets at that joint. The leakage paths between the outer and inner sleeves of the venturi are eliminated by applying a peripheral weld to the end edges of the flanges of the outer and inner sleeves. The leakage paths between the venturi and outer liner are minimized while simultaneously maintaining accurate venturi throat area relative to the cap centerbody by match drilling holes through the liner sleeve and the overlapped flanges of the venturi and followed by riveting the parts together.Type: GrantFiled: January 6, 2004Date of Patent: October 4, 2005Assignee: General Electric CompanyInventors: Donald Timothy Lemon, Ajay Kumar Gupta
